Yellow "undo deletion" bar does not scale to 1000 simultaneously deleted files

[msrex]

v4.5.4: when I delete 1000 files at the same time, the yellow "undo" bar at the top does not scale to fit. Also some heavy javascript action really bogs down FF. Better would probably be to list the first 5 and then say "... and 995 more", so the bar can stay a single line.

Reproduction steps:

• sync 1000 files into a folder
• mark all files
• select "delete marked"

=> See the yellow bar get very big and ugly.

This is now replaced with a new Trash App.

We still have the bar in other apps – does the issue appear there as well for mass deletion or is it already handled by saying »Deleted file1, file2 and 99 more«? cc @tanghus for Contacts, @georgehrke for Calendar.

@jancborchardt For Contacts there is a deletion queue which will be processed if the user doesn't press cancel within 10 seconds.
